MCR03EZPFX2552 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2552 is a 25.5 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives from active manufacturers that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (25.5 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1).

Parts are classified into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW060325K5FKEA (Vishay Dale), ERJ-3EKF2552V (Panasonic Electronic Components), and RMCF0603FT25K5 (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-2552ELF (Bourns Inc.) and RC0603FR-0725K5L (YAGEO).

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW060325K5FKEA, ERJ-3EKF2552V, or RMCF0603FT25K5. All three maintain active product status with established supply chains and full automotive qualification parity with the discontinued MCR03EZPFX2552.

For non-automotive applications or where moisture-resistant construction is acceptable, CR0603-FX-2552ELF and RC0603FR-0725K5L provide equivalent electrical performance and RoHS3 compliance with active availability.

All substitute parts are MSL 1 rated, indicating unlimited shelf life under standard storage conditions, and maintain identical thermal and electrical characteristics within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2552ELF or RC0603FR-0725K5L as direct replacements in automotive circuits?

A: These parts meet all electrical and mechanical specifications but lack AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive certification is not a design requirement.

Q: Are all substitute parts compatible with the original 0603 package footprint?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but all are compatible with standard 0603 PCB layouts.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CRCW060325K5FKEA, ERJ-3EKF2552V, RMCF0603FT25K5) carry AEC-Q200 automotive rating identical to the original part. Similar substitutes (CR0603-FX-2552ELF, RC0603FR-0725K5L) feature moisture-resistant construction and are suitable for general-purpose applications.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All listed parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring thermal performance equivalence.

Q: Which substitute has the highest inventory availability?

A: RMCF0603FT25K5 (Stackpole Electronics Inc) has 173,124 pieces in stock, followed by CRCW060325K5FKEA (Vishay Dale) with 61,925 pieces.
